UKSTUG meeting (*with corrected links*) - Christian Haider: How values make systems simpler - 25 Sep 2024 @ 7pm BST

by UK Smalltalk

Distinguishing between stateful Objects and Values has long been recognized as fruitful. Values are universal context-free abstractions that prevent side effects and allow for a functional programming style. Though programming languages provide simple Values like Integer and String, more complex Values are usually not supported. We show how to model complex structures as Values in Smalltalk, which allows for a simple and versatile implementation. The resulting Smalltalk systems are simple, clear and easily testable. Christian Haider [1] is the author of the PDFtalk library [2] used in smallCharts [3] and other projects. Underlying is a simple implementation of Values [4] which he uses extensively. Christian will show how Values make systems simpler and easier. Examples for some uses and the limits of the approach will be discussed. Since Values use only standard Smalltalk features, it can be used in most other Smalltalks. All of this code is available with MIT licence. This will be an online meeting from home.

Re: Jetbrains

by Pavel Mikhailovskii

Our language is indeed going to be quite different from the existing Smalltalk implementations. We are going to try many new things: better support for functional programming, static typing, even different syntax. We also consider it to be primarily a language for developing distributed systems. The existing Smalltalk implementations are very well suited for creating desktop applications, and we believe there's no need for yet another player in the field. We do want to provide Smalltalk IDE experience nonetheless. Can it still be called Smalltalk? That depends on how open-minded you are. (Can Java and Objective C be called mere ugly dialects of Smalltalk?). Alan Kay considers Smalltalk a continuous research, not a dogma, but there are, of course, practical reasons for not calling something a Smalltalk. Smalltalk has been evolving very quickly in its early years; Smalltalk-80 was *very* different from Smalltalk-71, why couldn't Smalltalk-2026 be as much different from Smalltalk-80? The existing implementations demonstrate how much can be achieved by continuing this branch of evolution; we want to explore new solutions, try new designs, make new mistakes. I am totally fine with people not considering our language a Smalltalk; I do think, however, that it shares a lot of core values with Smalltalk: minimalist approach to language design, application of the same patterns and concepts on all abstraction levels, focus on developer experience and the overall holistic approach, taking into account everything from VM implementation details to UI metaphors. An important difference is that we envision our language to be less dynamic and moldable—many people believe that those are the most important features of Smalltalk. Possibly, but they come at a high price in terms of performance, scalability, security and complexity. Again, we just want to explore new areas of the solution space.

To me this is a new language (it will not be a smalltalk) more functional, gradual typing = strong typing :) S > On 17 Sep 2024, at 13:46, Noury Bouraqadi <bouraqadi(a)gmail.com> wrote: > > Do you have any context? > Do they plan make yet another Smalltalk?
